```json
{
  "jsonrpc": "2.0",

## Why symbolList is rated Low

This tool retrieves market symbols/product information for stocks, crypto, forex, indices, futures, and funds without modifying, executing, or deleting data. It is purely informational and safe to expose to AI agents.

From the tool's own definition: "Tool name 'symbolList' and description indicate it queries product lists by type and region via GET request. The GET HTTP method and 'list' operation are characteristic of read-only data retrieval with no side effects."

## Use case

AI agents call symbolList to retrieve information from Itick without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Itick:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "symbolList": {}
  }
}
```
